GENERAL INSTALLATION NOTES Mount the intercom stations in locations that are safe and convenient for use. It is recommended that the master station be mounted inside the cab. Consider potential background noise that the hands free remote station might pick up. If excess background noise is picked up by the hands free remote station due to vibration, mounting it on a rubber pad can help reduce noise. Ensure a good ground connection. Isolate the intercom ground wire from other grounds that can be noisy (strobes, radios, priming motors, etc.). Make interconnecting cable runs as short as possible. Secure excess intercom cable in a figure 8 pattern. The foot switch option requires the installation of a single-pole single-throw switch (not supplied with intercom). 4

OPERATION Basic Two-Way System The basic two-way intercom system includes a master station with volume and Push-To-Talk (PTT) controls and a remote station that is operated hands free. The remote station is always transmitting unless interrupted by a transmission from the master station. Basic Three-Way System The basic three-way system includes two master stations (A and B) with volume and PTT controls and a remote station that is operated hands free. The remote station is always transmitting unless interrupted by a transmission from a master station. Master station A has transmit priority over master station B and the remote station. System Options Handheld Microphone Option This option is for installations in high noise areas. The microphone plugs into a receptacle on the station box. The system can be keyed to transmit with the microphone switch or the PTT button on the station box. Remote Station with PTT Button Option This option is for installations where a remote station with hands free operation is not required. The PTT button will have to be pressed for the remote to transmit. Foot Switch Option This option requires the installation of a single-pole single-throw foot switch (not supplied with intercom). A two conductor cable is wired at the foot switch and connected at the station box with a 2-pin Molex connector. The system can be keyed to transmit with the foot switch or the PTT button on the station box. 16
